Sorry ladies, if there’s music in the background you shouldn’t expect a grand performance from Mr. Justified.

Justin, who is dating Cameron Diaz, can’t “do” to things at one time and if there’s music in the background when he’s about to do the nasty he gets distracted.

He told Britain’s Dazed and Confused magazine: “I have trouble having sex to music because I’ll start picking out the chords.”

The 25-year-old, who releases his second solo album ‘FutureSex/LoveSounds’ next month, says his new record is packed with songs about sex for all those lovers able to get in the mood to music.

’tis a shame he isn’t one of them.

That doesn’t really speak too highly of Cameron’s bedroom prowess or his attention span.
